Abstract
The utility model discloses a swinging clamping device, and aims to solve the problems that a conventional clamp is inconvenient to operate and unstable in clamping and positioning and can only clamp a workpiece with a fixed size. The clamping comprises a base, wherein two opposite clamping jaws are arranged on the base, a clamping platform is arranged between the two clamping jaws, a workpiece clamping part is formed between the upper parts of the inner sides of the two clamping jaws and the clamping platform, the two clamping jaws can synchronously and vertically move along two sides of the clamping platform, the middles of the two clamping jaws are hinged through rotating shafts, one end of each rotating shaft is arranged in a sliding chute and can vertically slide along the sliding chute, a reset spring is arranged below the clamping platform located between the two clamping jaws, and a cam is arranged on the outer side of the bottom of one clamping jaw, is propped against the outer side of the bottom of the clamping jaw and is hinged with a piston rod of a cylinder. The clamping device is stable in clamping, convenient to operate and capable of clamping different sizes of workpieces.
Description
Technical field
The utility model relates to Machining Technology, is specifically related to a kind of clamping device that swings.
Background technology
The fixture of existing clamping workpiece to be processed, all generally by two jaws, workpiece to be clamped, but, in clamping process, often need two jaws to be operated to the clamping that could realize workpiece simultaneously, such fixture, operate very inconvenient, and can not guarantee two equal synchronization action holding workpieces of jaw, clamping position is unstable, and generally can only grip the workpiece of size.
Utility model content
The utility model provides a kind of clamping device that swings, to solve the problem that inconvenient operation, clamping position that existing fixture exists are unstable, can only grip dimension workpiece.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
Swing clamping device, comprise pedestal, pedestal is provided with two relative jaws, between two jaws, be provided with clamping platform, between described two jaw inside upper part and clamping platform, form piece-holder portion, two jaws can synchronously move up and down along the both sides of clamping platform, the middle part of two jaws is all hinged by rotating shaft, rotating shaft one end is arranged in a chute and can slides up and down along this chute, between two jaws, be positioned at clamping platform below be provided with back-moving spring, the bottom outside of a jaw is provided with the cam offseting with this bottom outside therein, the piston rod of cam and a cylinder is hinged.
The beneficial effects of the utility model: in this clamping device, the spring arranging between jaw has the effect of outside power all the time to two jaws, and this power can make to put outside jaw bottom, because jaw middle part is hinged, therefore two jaw tops are by interior pendulum, clamping work pieces; Piston rod band moving cam by cylinder rotates, and cam applies power to one of them jaw bottom, makes pendulum in this jaw bottom, and outside jaw top, pendulum unclamps workpiece.This fixture two jaws can synchronously move up and down, and change and clamp the grasping part of platform, thereby can clamp the workpiece of different size; This fixture is realized the clamping of workpiece by the effect of spring, and only just can unclamp workpiece by adjusting a jaw, easy to operate, and clamping is stable.
Further, be provided with jaw clamping force adjusting nut in the bottom outside of another jaw.The clamping dynamics of the adjustable jaw of clamping force adjusting nut to workpiece, further guarantees the stability clamping.
Further, described jaw is inverted "L" shaped.The structure of jaw inverted "L" shaped for the less workpiece of size, can clamp its upper surface simultaneously, clamps more firm.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model swings clamping device embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Swing clamping device as shown in Figure 1, comprise pedestal 1, pedestal 1 is provided with two relative jaws 2, each jaw is all inverted "L" shaped structure, between two jaws, be provided with clamping platform 3, between two jaw inside upper part and clamping platform 3, form workpiece 10 clamping parts, two jaws can synchronously move up and down along the both sides of clamping platform 3, the middle part of two jaws is all hinged by rotating shaft 4, rotating shaft 4 one end are arranged in a chute (not shown) and can slide up and down along this chute, between two jaws, be positioned at clamping platform 3 below be provided with back-moving spring 5, the bottom outside of a jaw is provided with the cam 6 offseting with this bottom outside therein, the piston rod 8 of cam 6 and a cylinder 7 is hinged, be provided with jaw clamping force adjusting nut 9 in the bottom outside of another jaw.
This clamping device operation principle is as follows: the spring arranging between jaw has the effect of outside power all the time to two jaws, and this power can make to put outside jaw bottom, and because jaw middle part is hinged, therefore two jaw tops are by interior pendulum, clamping work pieces; Piston rod band moving cam by cylinder rotates, and cam applies power to one of them jaw bottom, makes pendulum in this jaw bottom, and outside jaw top, pendulum unclamps workpiece.
Claims (3)
1. swing clamping device, comprise pedestal, pedestal is provided with two relative jaws, between two jaws, be provided with clamping platform, between described two jaw inside upper part and clamping platform, form piece-holder portion, it is characterized in that, two jaws can synchronously move up and down along the both sides of clamping platform, the middle part of two jaws is all hinged by rotating shaft, rotating shaft one end is arranged in a chute and can slides up and down along this chute, between two jaws, be positioned at clamping platform below be provided with back-moving spring, the bottom outside of a jaw is provided with the cam offseting with this bottom outside therein, the piston rod of cam and a cylinder is hinged.
